MOTOR FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 400,507, dated April 2,1889.

Serial No, 294,203. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM H. STRIoK- LER and JAMES S.BRADDOCIQOitiZQDS of the United States, residing at Mount Pleasant, inthe county of Westmoreland and State of Pennsylvania, have invented newand useful Improvements in Motors for Chorus, of which the following isa specification.

The invention relates to improvements in' motors for churns; and itconsists in a certain novel construction and combination of devices,fully described hereinafter in connection with the accompanyingdrawings, and specifically pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a churn-motorembodying our invention. Fig. 2 is a vertical longitudinal sectionalView of the same. Fig. 3 is a transverse central sectional view thereof.Fig. 4 is a rear view. Fig. 5 is a front view, partly broken away, of aportion of the motor to show the device for winding the drum and spring.Fig. 6 is a plan View of the same, showing a winding-key applied in theoperative position to the arbor.

Referring by letter to the drawings,A designates the supporting-framefor the operating mechanism, which is provided with vertical standards aa, respectively, at its front and rear sides, and B designates atransverse horizontal verge, which is mounted in suit-able bearings inthe said standards.

0 O designate vibrating arms, secured at their centers to the verge nearthe ends of the latter and beveled on their upper edges from the centertoward the ends, and D designates the churn-tub, which bears on theupper edges of the said arms andis secured thereto'by suitable means.The bottom of the churn-tub is inclined upward from its ends toward thecenter to fit the upper edges of the arms 0.

A suitable cover, E, is fitted in the opening e in the upper side of thechurn-tub, and breakers F F depend from the opposite sides of the saidopening and extend transversely across the tub. These breakers consistof a series of vertical bars, ff, connected at their ends by thehorizontal bars f f, and they are designed to swing to and fro as thechurnbody is oscillated. One of the arms Ois provided with vertical ears0 0, having inwardlyprojecting pins 0 c, which fit in sockets in thesides of the churn-tub, and the other arm is provided with a hasp 0 or asimilar securing device.

On a horizontal arbor, G, which is mounted in suitable'bearings in thesupporting-frame, is arranged the scape-wheel H, which is engaged by apallet, I, at an intermediate point of the verge, and K designates apower-shaft, mounted on the supporting-frame and provided with a mainwheel, K, which meshes with a pinion, G, on the arbor G. v Anoperating-spring, L, is arranged on the power-shaft to rotate the same,and thereby cause the rotation of the arbor and the scapewheel, and Mdesignates a drum mounted on the shaft K adjacent to the main wheel, andprovided with a ratchet-Wheel, k, which is engaged by a pawl, It, on thesaid wheel, to lock the drum rigidly on the shaft. A cord, 0, is woundon the said drum,passes around an idler-pulley, P, on the arbor G,passesover a pulley, p, at the upper end of the standard a, passes through thepulley-block P, and 1s attached at its end to the said standard. Aweight, Q, is engaged with a hook, q,on the said pulley-block to assistthe spring L 111 the rotation of the power-shaft. The spr ng and theWeight may be wound up by rotatlng the said shaft by means of a key, 10(Shown detached in Fig. 6.) R designates a short spindle mounted on thesupporting-frame and provided with a pinion, 1, which meshes with asimilar pinion, r, on-the drum, whereby the said drum may be rotatedindependently of the main shaft. This construction is designed to enablethe cord to be wound on the drum in the opposite direction to that shownin the drawings, whereby the weight will act against the spring in orderto reduce the power thereof when the latter is too great.

S designates a pendulum provided at its upper end with a hook, s,engaged with a suit able pin, 3', and T designates a depending arm onthe verge, which is provided at its lower end with a finger fitting in-alongitudinal slot, S, in the pendulum.

The pendulum is provided near its lower end with a series ofperforations, U U, and the pendulum-bob V, which fits on the pendulum,is provided with a perforation, v, adapted to register with either ofthe perforations in the pendulum. A pin,V, engages the said registeringperforations to secure the bob at the desired point of the pendulum.

The operation of the improved churn will be readily understood from theforegoing description. The churn-tub, which is mounted on the verge, isoscillated by the force of the spring and weight acting through thegearing and escapement, and the contents of the tub are dashed from oneend thereof to the other over the double-inclined bottom, the breakersserving to increase the agitation of the same. The bob is lowered orelevated on the pendulum to suit the weight of the contents of the tub,the object thereof being to counterbalance the weight of the contents.

\V W represent vertical buffers arranged under the ends of the churn-tuband provided at their upper endswith the coiled spring 10 w, againstwhich the ends of the tub alternately strike as the latter isoscillated. The springs aid in changing the direction of the swing ofthe pendulum and prevent the same from swinging too far.

Having thus described the invention, we claim 1. The combination of thetub mounted on a verge which is provided with a pallet engaging asuitable scape-wheel, and the powershaft geared to the shaft of thescape-wheel, substantially as specified.

2. The combination of the verge carrying a churn-tub and having a palletwhich engages a suitable scape-wheel, the power-shaft geared to theshaft of the scape-wheel and provided with a power-spring to rotate theshaft, the drum mounted on the power-shaft and adapted to be lockedrigidly thereto, and the cord coiled on the drum and provided at itsopposite end with a weight, substantially as specified.

3. The combination of the verge carrying a churn-tub and having a palletwhich engages a suitable scape-wheel, the power-shaft provided with aspring and geared to the shaft of the scape-wheel, and the buffersarranged under the ends of the churn-tub and provided at their upperends with coiled springs to to, which are adapted to be alternatelycompressed by the churn-tu b, substantially as specified.

4. The combination of the verge provided with the rigid vibrating arms 0C, the churntub removably secured to the said arms, the pallet arrangedon the verge and engaging a suitable scape-wheel, and the power-shaftgeared to the arbor of the scape-wheel, substantially as specified.

5. The combination of the verge provided with the arms 0 O, beveled ontheir upper sides froin'their centers toward the ends, the churn-tubprovided with a double inclined bottom'fitting on the upper edges of thesaid arms and removably secured thereto, the escapement arranged asdescribed, and the power-shaft geared to the arbor of the scapewheel,substantially as specified.
